SUGAR-GRANULATOR.

SPECIFICATION forming part of Letters Patent No. 541,010, dated .T une 11,1895. Application led February ZS, 1895. Serial No. 540,076. (N model-l To LZZ whom t mag/concern: l Be it knownk that we, WILLIAM W. REID, residing at New Orleans, in the parish of Orleans, and BENJAMIN W. COOK, residing at Port Allen, in the parish of Westv Baton Rouge, State of Louisiana, citizens ot' the United States, have invented certain new and useful Improvements in Sugar-Granulators; andv we do herebydeclare that the following ro is a full, clear, and exact description of the same, reference b eing had to the annexed drawings, making a part of this specification,

and tothe gures of reference marked thereon.

It is the purpose of our invention to pror 5 vide an apparatus for granulating sugar which f shall be rapid and efficient, in operation, andsimple and comparatively inexpensive in construction, whereby sugar may be granulated and perfectly dried as it comes from the suzo gar-making mechanism.

The invention consists in the several novel features of construction and new combinations of parts hereinafter fully described and then particularly pointed out and defined in the claims concluding this specification.

To enable those skilled in the art to fully understand and to makerand use our said invention, we will new describe the same in detail, reference being had to the accompany- 3o ing drawings, in which- Figure 1 is a front elevationshowing an apparatus in which our invention is incorporated. Fig. 2 is a central vertical section of the apparatus shownin Fig. 1. Fig. 3 is a plan View of the same,the'hopper and crushing-rolls being omitted. Fig. 4 is a horizontal section upon the line 4 4, Fig. 2, showing the door partly opened.

The Vreference-numeral 1in said drawings 4o indicates a cylindrical, upright casing, having a closed lower end which is mountedin arigid base 2. Throughout the length of said casing extends a tubular shaft 3, supported in a bearing 4 below the base 2, and in a spider-bearing 5 at the open top of the casing. The tubular shaft is capable of revolving in said bearings and is driven by a pulley 6, which is belted to any suitable source of power.

Upon the interior of the cylindrical casing 5o 1, at suitable and regular intervals, are arranged hopper-shaped sections 7, rigidly secured by their edges to the inner face of the casing From this point of attachment each section extends downward and inward, terminating at the contracted lower end, which is open. Each section represents, in other words, a frustum ofan inverted, hollow cone, the truncated end of each being in, or nearly in, the same plane with the attached edge of the next section below. Upon the tubular 6o shaft are rigidly mounted a series ot' horizontal disks 8, arranged at points between the upper and lower open ends of the sections 7,

and havinga diameter somewhat greater than the contracted lower ends of said sections. A sufficient annular spaceis provided between Vtheedge of each disk and theinner face of each hopper-shaped section 7 for the passage of the granulated sugar. i

In the lower end of the cylindrical casing 1 is arranged a chamber 9, through which the lower, tubular portion of the shaft 3 passes. The shaft is packed through this chamber by means of glands 10, which are adjusted by bolts 12, to give as nearly as possible an air- 75 tight joint. In the lower end of the tubular shaft are formed openings 13, through which heated air, whichis supplied tothe chamber 9 by a tube 14, may pass into the tubular shaft 3. In said shaft are formed numerous small 8o apertures 15, by which the heated air may escape in all directions into the interior of the cylinder.V A separate tube 16 may also be packed in the upper end of the shaft and extended nearly to the lower end of the tubular portion, and either tube may be used tosupply the heated air.-Y The means for heating and forcing the same may be of any ordinary form and require no specific explanation.

At a suitable point above the open top of 9o the cylindrical casing are arranged a pair of crushing rolls 17. Over these rolls is a l1op per 1S, preferably arranged at such a point that it can receive the sugar as it comes from the sugar making mechanism. By passing between said rolls the lumps are crushed and the large crystals broken up. The sugar then passes to the granulator, entering its open upper end and falling upon the upper disk.

The tubular shaft 3 being in rapid revolution, roo

the sugar isv immediately thrown outward against the inner face of the cylindrical casing and drops into the first hopper-shaped section 7. Sliding down its Wall it is poured upon the second disk, and the previous operation is repeated. During the operation heated air is poured through the numerous apertures in the tubular shaft and is forced to pass upward and escape through the open top of the casing. The sugar moving in the opposite direction is caused to travel the greatest possible distance in order to reach the lower end of the casing, and is, moreover, kept in constant agitation so that the hot air can reach every granule and no lumps, or adhesions, can be formed. After passing through the last section 7 it falls upon an inclined chute 19 and passes out of the casing through an opening 20. By the time it reaches the latter point it isthoroughly dried and granulated.

The cylindrical casing is provided with a hinged section 21, by which access may be had to the interior, and transparent panes 22 may be inserted at suitable points, to permit inspection of the interior.

l. In a sugar-grannlating apparatus, the combination with a cylindrical casing having a series of interior rigidly attached, hoppershaped sections,of a tubular shaft passing con. centrically through said casing and through central openings in said sections, said shaft being provided with a series of disks arranged to revolve within but out of contact with the hopper-shaped sections, and being provided also with numerous apertures for the passage of hot air into the casing crushing rolls adapted to deliver sugar to the open top of the casing, and means for supplying air to the tubular shaft, substantially as dcscribed.

2. In a sugargranulating apparatus, the combination with a cylindrical casing having a hinged section and provided with a series of interior, hopper-shaped sections secured by one edge to its inner face, of a concentric, tubu lar shaft provided with a series of vdisks arranged within, but out of contact with the hopper-shaped sections, the lower end of the casing being provided with a chamber through Which the tubular shaft is packed and from which it :hay receive hot air under pressure which escapes through apertures in said shaft and crushing rolls arranged to deliver sugar to the open top of the casing, substantially as described.

In testimony whereof we have hereunto subscribed our names in the presence of two Witnesses.
